The mother of four from South Penrith has recently claimed a small victory over Facebook after the social media giant was forced to recognise "Batman" as her real surname and not a prankster's pseudonym.

Ms Batman registered her account under Belinda Batman in 2008 but was notified last month she could no longer be registered because it was a fake name.

"I used Facebook to reach out to all my family - the Batman family - across Australia and overseas, and all of a sudden Facebook wouldn't let me use my real name."

Ms Batman registered the original Batman account in 2008 but had to verify her name by sending in a photocopy of her licence and even operate under a fake name - Belinda XBatmanX - to keep her account open.

She was finally informed she could continue to use her profile with her surname.

The battle is just one of many odd anecdotes for Ms Batman, who can trace her family history back to one of Australia's most prominent Batman families as a relation to John Batman, best known for his role in the founding of Melbourne.
